光波相位梯度对负折射和负反射的影响
The influence of light phase gradient on negative refraction and negative reflection
摘要
Abstract
For further study on the laws of anomalous refraction and reflection,the Matlab software were used to simulate the generalized Snell's law.The results of simulation show that the reflected light disappeared when the incident angle is greater than critical angle when it decreases with the increase of phase gradient turned negative,negative reflection phenomenon occured.Refraction of light disappears and total reflection appears if the incident angle is greater than critical angle when it decreases with the increase of phase gradient until it was negative,negative refraction phenomenon occured.As choosing appropriate phase gradient,negative reflection and negative refraction may occur.These phenomenon will be applied widely in cloaking,modulating phase,controlling light beams.关键词
